真正dog and lemon guide网上查我要付钱的。但是2010书版,我记得大部分标志、雷诺、爱快罗密欧、菲雅特、宾弛和大众车都是not recommended或者avoid like the plague,一些Mini、宝马和士柯达的评级是okay但还是爆料说出一大堆隐疾。那本书我在墨尔本丢了作者: kobemvp 时间: 2012-9-4 14:40:21
top gear和auto car给这车评价都不低。。。作者: 南极熊 时间: 2012-9-4 15:35:40
You probably think that modern diesels are better than earlier models but you may be wrong. Although many improvements have been made over the years, big, reliable, chugging diesels are rapidly going the way of the dinosaur. The ever-growing need for better fuel economy, less pollution and greater performance has meant that diesel engines have been pushed beyond their limits by over-eager vehicle manufacturers.
Traditional diesel engines were heavily built and rarely worked very hard. Because they rarely worked very hard, the engine lasted a long time.
By comparison, most modern diesels have turbochargers – giant air pumps – pushing pressurised air through them to make the engine work at least a quarter harder. As the engine works at least a quarter harder, so the engine parts and cooling system have to work at least a quarter harder. Some of this extra strain can be taken up with skilful engine designs and higher quality parts, but there’s a limit to this.
The latest generation of diesel engines, termed common-rail diesels, are the most efficient diesel engines ever made, and when fitted to a car offer good levels of power and acceleration comparable to petrol engines.
However, many turbocharged common-rail diesel engines work harder than any other diesels in history. No matter how solidly they are made, we do not believe that they will last as long as their less hard-working cousins of old.
France is the world centre for small diesel engines. Diesels account for most of the new cars sold in France and in Europe generally.
There is already plenty of evidence of problems with the new generation of European common rail diesel engines, even when relatively new. However, there are far worse problems down the track, after the vehicles leave warranty. European diesel engines (like their petrol siblings) are designed to be used in one vehicle for a fixed period of time and then disposed of. They are computer controlled and everything from the high tech fuel pumps to the exhaust system is designed to work together as one whole unit. Without the computer and the sensors in the exhaust pipe, the diesel will not run properly.
The European carmakers know this of course – in five or ten years’ time when their diesel becomes uneconomic to fix or will no longer pass emissions checks, they’ll be waiting around to sell you a whole new vehicle. The rest of the car will probably be junk.
Peugeot diesels use a silicon carbide honeycomb filter that absorbs pollution, then every 500km or so the filter system oxidizes the absorbed pollutants by injecting a small amount of fuel and a rare-earth-derived additive called Eolys to superheat the exhaust and burn off the soot left behind by burning diesel.
Very clever no doubt, and we believe Peugeot’s claim that the system eliminates 95% of pollution – when new. However, given Peugeot’s woeful reputation for reliability even with existing technology, hands up everyone who thinks this system will still be working reliably and economically in ten years’ time? Thought not.作者: 爱国爱港 时间: 2012-9-4 21:33:13
